Abstract

피에조 일렉트릭 변환기에 있어서 압전 비활성 영역(11)이 구동부(22)와 전력 발생부(31) 사이에 제공되었다. 전력 발생부(31)은 피에조 일렉트릭 몸체(1)의 종방향으로 연장되고 자신의 주표면 위에서 한 쌍의 상부 및 바닥 전극(7T) 및 (7B)를 제공받는다. 구동부(22)는 폭방향에 수직한 측면 위에서 측면 전극(5)를 제공받는다. 또 다른 전극(50T) 및 (50B)는 전극(7T)및 (7B)에 평행하게 되도록 제공된다. 전력 발생부(31)은 피에조 일렉트릭 몸체의 폭 방향 및 두께 방향으로 편극되고, 구동부 (22)는 피에조 일렉트릭 몸체(1)의 폭 방향으로 편극된다. 구동부(22)의 전극(50T)(50B)와 전력 발생부(31)의 전극 (7T)(7B) 사이에 제공된 압전 비활성 영역(11)의 폭을 조절함으로써 변환비가 조절될 수 있다.In the piezo electric converter, a piezoelectric inactive region 11 was provided between the driver 22 and the power generator 31. The power generating section 31 extends in the longitudinal direction of the piezo electric body 1 and is provided with a pair of top and bottom electrodes 7T and 7B on its main surface. The drive part 22 is provided with the side electrode 5 on the side surface perpendicular to the width direction. Still other electrodes 50T and 50B are provided to be parallel to the electrodes 7T and 7B. The power generation unit 31 is polarized in the width direction and the thickness direction of the piezo electric body, and the drive unit 22 is polarized in the width direction of the piezo electric body 1. The conversion ratio can be adjusted by adjusting the width of the piezoelectric inactive region 11 provided between the electrodes 50T and 50B of the driver 22 and the electrodes 7T and 7B of the power generator 31.
